Coherent phonon control beyond amplitude saturation in a sliding ferroelectric
Jan Gerrit Horstmann, Christoph Emeis, Andrin Caviezel +5
The breakdown of Hooke's law marks the onset of nonlinear behaviour: when displacements become large, restoring forces weaken and conventional proportionality fails. In quantum mat…
Optical switching of ferro-rotational charge-density wave states
Wayne Cheng-Wei Huang, Sai Mu, Gevin von Witte +7
Tailored optical excitations can steer a system along non-equilibrium pathways to metastable states with specific structural or electronic properties. The light-induced hidden stat…
Distribution of antiferromagnetic rare-earth domains in multiferroic DyTbFeO
Yannik Zemp, Ehsan Hassanpour, Jan Gerrit Horstmann +6
In many multiferroics, rare-earth and transition-metal orders exist side by side. For analyzing their interaction and its consequences for the multiferroic state, the associated do…
Dynamic control of ferroic domain patterns by thermal quenching
Jan Gerrit Horstmann, Ehsan Hassanpour, Yannik Zemp +3
Controlling the domain structure of ferroic materials is key to manipulating their functionality. Typically, quasi-static electric, magnetic, or strain fields are exploited to tran…
